Description

Technical Field

[0001] The utility model relates to the technical field of arc rolling machines, in particular to a double-roller arc rolling machine. Background Art

[0002] The arc rolling machine is composed of three rollers, which are usually used to process rolled plates. There is an upper roller and two lower rollers. The plate is clamped in the middle. The rollers are used in pairs. Some double-roller arc rolling machines include a base with support plates symmetrically arranged on the top of the base. Three arc rolling rollers are installed between the support plates to rotate symmetrically front and back and up and down. The roller shafts of the arc rolling rollers are connected to motors on the outsides of the support plates. The utility model uses a cooling component to drive the rotating shaft to push or pull the connecting rod with the power generated by the dual-axis motor, thereby pushing or pulling the piston to move, which can push water into the cooling pipe to cool the air in the air duct. By cooling the device, the production efficiency is improved. The arc rolling rollers are installed on In the device, the arc rolling roller bends the plate through the contact rolling pressure between the arc rolling roller and the plate. The surface of the arc rolling roller is severely worn after long-term use. In order to improve the arc rolling flatness of the subsequent plates, the arc rolling roller needs to be replaced. However, the arc rolling roller itself is fixed by a bearing seat, and the base and the top cover of the bearing seat are connected and fixed by multiple sets of bolts. When replacing the arc rolling roller, it is necessary to first remove the multiple sets of bolts on the bearing seat, and then remove the arc rolling roller from the bearing seat and replace it, and then fix the bearing seat again with bolts to fix the replaced arc rolling roller. This method requires multiple disassembly and assembly of the bolts, which is cumbersome and needs to be improved. Utility Model Content

The laser sensor 13 is arranged on the upper side of the slide 3 on the left side. The laser sensor 13 is bidirectionally electrically connected to the single-chip microcomputer 2. When using the roller arc rolling machine, the plate passes through The gap between the pressure rollers 5 is formed, and the pressure rollers 5 cooperate with each other in pairs to bend and roll the plate. The single-chip computer 2 starts the motor 2 12 so that its output shaft drives the adjacent rotating shaft 4 to rotate. The rotating shaft 4 drives the rotating shaft 4 on the rear side of the lower right end to rotate synchronously through the belt transmission between the pulley 9 and the belt 10, thereby making the two pressure rollers 5 on the lower side rotate synchronously. The pressure roller 5 on the lower side bends and rolls the plate through contact friction. The belt transmission diameters between the two pulleys 9 are different, thereby realizing the belt transmission of the belt 10. The single-chip computer 2 starts the motor 18 to output The shaft drives the stud 7 to rotate, and the stud 7 is connected by a thread, so that the slide 3 drives the upper pressure roller 5 to move vertically along the slide, and the bending curvature of the plate is adjusted according to demand.
